Design lowpass filters. The example highlights some of the most commonly used command-line tools in the DSP System Toolbox. Alternatively, you can use the Filter Builder app to implement
Use System objects to do streaming signal processing in MATLAB. The signals are read in and processed frame by frame (or block by block) in each processing loop. You can control the size of each
Visualize and measure signals in the time and frequency domain in MATLAB using a time scope and spectrum analyzer.
Lowpass filter a noisy signal in MATLAB and visualize the original and filtered signals using a spectrum analyzer. For a Simulink version of this example, see Filter Frames of a Noisy Sine
Model an algorithm specification for a three band parametric equalizer which will be used for code generation.
Use the Streaming Testbench Generator app to generate DSP algorithm testbenches. The DSP algorithm generated in this example is similar to the algorithm in the Filter Frames of a Noisy Sine
Design filters for use with fixed-point input. The example analyzes the effect of coefficient quantization on filter design. You must have the Fixed-Point Designer software™ to run this
Demonstrates how to generate HDL code for a programmable FIR filter. You can program the filter to a desired response by loading the coefficients into internal registers using the host
To estimate the transfer function of a system in MATLAB, use the dsp.TransferFunctionEstimator System object. The object implements the Welch's average modified periodogram method and
Alternately, you can compute the power spectrum of the signal using the dsp.SpectrumEstimator System object. You can acquire the output of the spectrum estimator and store the data for
You can design and implement the FIR multirate filters in Simulink using the FIR Decimation, FIR Interpolation, and FIR Rate Conversion blocks. When you set Coefficient source to Dialog
Sample rate conversion is a process of converting the sample rate of a signal from one sampling rate to another sampling rate. Multistage filters minimize the amount of computation involved
To implement an FIR Decimator, you must first design it by using the designMultirateFIR function. Specify the decimation factor of interest (usually greater than 1) and an interpolation
Use the MATLAB Compiler™ to create a standalone application from a MATLAB function that uses System objects from DSP System Toolbox™.
To view the power spectrum of a signal, you can use the dsp.SpectrumAnalyzer System object™. You can change the dynamics of the input signal and see the effect those changes have on the power
